To all whom it may concern:

Beit known that l, GARDNER E. WHEELER, a citizen of the United States, 'residing in New Haven, county/'of New Havern anti State of Connecticut, have invented certain new and useful ln'iprovements in Automobile-Radiators, of vwhich the following is a full, clear, and exact description.

This invention relates to automobile radiators, and one of the primary objects of .the intention is to provide a radiator combining a maximum ambunt of radiating surface with a minimum amount of wind .resistance.

lt is also aimed to provide a simple and effective arrangement of the tubes or cooling elements in pointed or substantially llsh'aped section or core.

To thcseand other ends, the invention consists in the'novel features and combinations of parts to be hereinafter described and. claimed..

ln the accompanying drawings, Figure is a perspective view of a radiator embodying my invention, with the tube section only partially shown; Fig 2 is a side elevation of the radiator; Fig. 3 1s a horizont-al section through the same; Fig. 4 `is a rear eleration of the device; Fig. 5 is a detail plan view of ai group of tube elements, showlng the preferred arrangement of the tube ele-v ments in the radiator jacket or casing; and Fig. 6 is a diagrammatic edge view of one of the vertically arranged tube elements.

Referring to the drawings, 10 denotes generally a tube section, which instead of being fiat, as heretofore, is built up substantially in the form of a V.' This provides a comparatively sharp 'nose or ridge, at the front, directed vertically, from which the upright side walls of the tube section ln the preferred form, the tube section 10 isV-shaped at its -rear surface as well as .at the front surface,yas shown in Fig. 3, as it is unnecessary to extend the rear ends of the tubes vback to a common vertical plane.- A sufficient amount of radiating surface may be obtained by the use of comparatively short tubes or eletion. 10, and providing a bottom water chamber. The portion 12 is generallyll/shapcd at the front to conform to the tube section,

but its rear edge is preferably'fiat, as shown in Fig. 3, thereby giving it a substantially triangular form. Rising from the base por* tion 12, at the sides of the .tube section 10, are' narrow' frame portions 13, conforming` to. and covering the ends or side edges ol the tube section, and these' portions 13 join at their upper ends the lupper portion 14 of the casing or jacket. This upper portion 14 of the casing or jacket provides the custo-niary'water chamber above the tube section, 4and is provided with a filling connection 15, which may be of the usual form. The rear wall 16 of the chamber 14 may be substantially fiat, as customary, and in parallelism with the rear edge of the base poi'- tio-n 12. Connection with the engine is made by means of pipe connections-'17 and 18 applied at the rear -of the base portion 12 and upper water chamber 14 respectively.

Although the upper chamber 14 of the casing 11 may be flat at the rear, as customary, it is extended forwardly and down-` wardly at the front, and provided with 'a generally l/shaped .front edge portion 19,'

so that said portion 14 conforms to and 'overlies the upper edge of the tube section 10. Hence the upper water chamber, like the lowerI water chamber, is of a generally triangular shape in horizontal section. The center rear portion of the part 14, adjacent the filling connection 15, forms a sort of apex, from which the front wall of the part 14- is directed downwardly at a comparatively sharp angle, as shown in Fig. 2, to meet the upper edge of the V-shaped tube section. In the embodiment shown, the front wall of the part 14 is slightly rounded at a point above its lower front edge portion in order to merge together the angular lower front edge portion with the upper curved rear edge portion, as shown in Fig.

1, but this is' not essential in all aspects of the invention.

The tube section 10, shown in Figs. 3 and 5, is preferably formed of tubes directed forwardly and rearwardly, said tubes being preferably manufactured in individual vertical tube elements 20"l (Fi n.6), extendilnthroughout the height of t e tube section, and assembled side by side, to provide intermediate water spaces 20, in communication with the upper and lower water chamto maire all of the tube elements of the same x leug'li, stated, and to Varrange their front ,r ends in stepped fashion, or iu lou, shown, the ridge or apex of the Hug; Jformed by a single vertical tube eleu shown in Fig'. 3. Preferably-tile me elements are provided with enlarged ccrresriouding in, .length to about twice f oi' overlap of tbe next adjacent t as shown in Fig, 5, so that the u may be easily aud rigidly pom 'each other to create the several 7iue water spacee. i be manifest that owing 'to the coniou oi the radiator easing at the botaud aides, and at the upper rear edge, c radi. tur be used iu existingA automobiles without necessitating any inodilicatiou of the bonnet. Ubviously, the decrease of the 'Wind resistance is not only brought f -it by tapering the tube section toward ont of the automobile, but also by the A liaped form of the easing; or jacket, and lie slautiug' oi: the upper front part of the aging iu u forward and downward direc4 ion wit-l1 reference to the upper rear edge tbc. casing. In tlie embodiment shown, tbe upper portion lll of the casing or jacket fauted forward and downward on a o u, line at its. middle or cental lpart j, and ut a comparatively sharp aun j it will be understood that l do not luuit myself to any particular angle, or to a rectilinear slant oi' the central front porriou o1 the casing above the tubes.
